NUK teats are designed to simulate the mother's nipple during breast-feeding.

It helps to stimulate muscle activities of jaw and palate in the natural development of the oral cavity of babies. Its feed hole is so positioned that it points upwards towards the baby's palate. In this way the milk is mixed with saliva before ingestion and it is good for digestion.

With the NUK Air System, the teat can prevent excessive swallowing of air which is thought to be a common cause of colic.
